RE: Buddy Cam Core One Wifi connection failed after update to FW 3.1.2

I've contacted with the support and they told me this:

We are aware of the issue, and we are working on a fix. So far, it seems like the issue is caused by the "_" character in the SSID or the password.

 

Stay tuned 🙂

Regards,

That tracks with my experience, I added my own experience yesterday (that is still awaiting moderation for some reason) that mine stopped working even though my wifi SSID and password were both alpha-numeric.

After double-checking, it turns out my SSID actually has a "_" character in it, so this explains why my camera is affected.

I did have a _ in my ssid.

Thanks for the info! 

Just an addition if Prusa is reading this topic. My wifi does not have that character. And I have tried with a new wifi hotspot where ssid and pwd only included lowercase letters and numbers.

Hey, I’m seeing the exact same issue. My SSID and Wi-Fi password don’t contain any special characters either — it's just on the longer side. I also downgraded, and that fixed it. Thanks for the tip! I’d already spent way too much time trying to figure this out…

I'm already in contact with support and will also point them to this thread.

I just got finished with a support chat and they're sending me a new camera after failing to get it fixed.  My ssid is just alpha (and short), password is longish but only alpha.  Tried making a new ssid with short password too, no luck.

Then I find this thread -- downgraded to 3.1.0 and boom, it works.

Is it a permanent solution though?  The docs for the buddy camera says it will connect and look for upgrades every 4 hours.  Won't it just upgrade to 3.1.2 and break again?
